The Merseysiders are among a cluster of clubs who have enquired about taking the Costa Rica international on a season-long loan as they attempt to bolster their strike force.

However, Arsene Wenger has rebuffed all offers and wants to hold on to the 22-year-old at least until January.

Campbell will be integrated into the Arsenal senior squad for the first time since joining the club in 2011, following loan spells at Lorient, Real Betis and Olympiakos. He will join Olivier Giroud, Yaya Sanogo and new signing Alexis Sanchez in battling for the central striker's role.

Speaking at his Friday press briefing ahead of Saturday's Premier League curtain-raiser against Crystal Palace, Wenger said Campbell had "matured a lot" and figured in his plans for the forthcoming campaign.

"He has come from a non-competitive world to a world with hyper-competition," he said. "He has adapted slowly, but has adapted very well, he has a very good spirit and attitude.

"He is a member of my squad at the moment, he had a good preparation and played well against Benfica.

"In training he is very focused and eager to do well. I would like to keep him."

The Arsenal boss is expected to review the situation in the winter window depending upon the success of Campbell and his fellow front men during the opening months of the season.

Liverpool are working on signing a striker to provide competition for Daniel Sturridge and Rickie Lambert. They have held two rounds of talks with Samuel Eto'o this week after pulling the plug on a €10 million move for Loic Remy.
